IMPROVEMENT IN LANTERNS FOR STREET-LAMPS.

Specification forming part of Letters Patent No. 176,164, dated April18, 1876; application filed March 6, 1876.

To all whom it may concern:

Be it known that I, AUGUSTUS S. BUNKER, of Lawrence, in the county ofEssex and Commonwealth of. Massachusetts, have invented an ImprovedLantern for StreetLamps.

. The object of my invention is to so construct a lantern that the panesof glass can be removed and inserted quickly and at pleasure, either torepair breakage or for the purpose of cleaning, (no putty being used totighten the same.)

This I accomplish by so constructing a lantern'fra ne that two or moreof its four corners can be removed, (being opposite, if two are used,)and having its flanges so constructed that they shed down and over apane, forming a groove for the purpose of receiving the same, thusallowing a pane to he slipped from its frame, or in case of breakage, anew one inserted; and I do declare that the following is such a full,clear, true, and exact description thereof that others skilled in theart to which it appertaius can make and use the same, reference beinghad tothe accompanying drawings for a more complete description thereof,like letters indicating the same parts in each of the drawings, ofwhich- Figure 1 is a View of a lantern-top with my improvement attached;Fig. 2, a section of a corner with my improvement applied, taken at a aand Fig. 3 shows the eye, the springcatch, a corner with its hooks andthe flanges.

A is a lantern-frame, designed to hold the pane; B, a pane of glass,designed to form a lantern; G, a corner, formed by soldering a piece-oftin, bent to form an angle, to a rod,

designed to be removed when it is desired to To use my improved lantern,should it be desired to remove a light of glass for the purpose ofcleaning or other purpose, or to repair breakage, raise the catch D andremove the corner (3, when a light can be easily removed or replaced.After being replaced, place the corner 0 back, securing by the eye E andcatch D.

I have been informed that it is not new to construct street-lamps with amovable corner, and I make no claim thereto; but- I am not aware thatprevious to my said invention lanterns have been constructed as hereindescribed.

I claim as my invention-- The combination of the frame A, the-spring D,the eye E, the corner (J, and the flange F F, in a manner and for thepurpose substantially as herein described and set forth.
